SM U-152

U-152 was actively employed in the Atlantic during the last year of the conflict. Among her victims were two American schooners, Julia Frances (sunk on 27 January 1918) and A.E. Whyland (sunk on 13 March 1918), the Norwegian barque Stifinder (boarded and scuttled on 13 October 1918), the Spanish Giralda (sunk on 25 January 1918), and the U.S. Navy cargo ship USS Ticonderoga. The latter was sunk, after a two-hour gun battle, with heavy casualties among her crew and passengers, on 30 September 1918. The previous day, 29 September, the submarine had also fought a gun battle with the Navy oiler USS George G. Henry, but despite being badly damaged the American ship escaped.

After returning to Germany in November 1918, at the end of her final wartime cruise, U-152 was surrendered to the Allies at Harwich on 24 November 1918 in accordance with the requirements of the Armistice with Germany. She was exhibited at Tower Bridge in London in December 1918, and then laid up at Portsmouth. On 30 June 1921, she was towed out into the English Channel and scuttled.[2][3]
